Application filed December 9, 1912. Serial No. 735,797.

To all whom it may concern:

Be it known that I, ALEXANDER JosnrH ADOLPHE BRUET, a citizen of theFrench Republic, residing at 26 Rue de la Legion dHonneur, St. Denis,Seine, France, have invented certain new and useful Improvements inAuxiliary Raising and Centering Vehicle-Rims, of which the following isa specification.

This invention relates to a device for enabling a damaged or deflatedwheel to be raised and centered automatically.

The object of the invention is to provide a device of this characterwhich will center and raise a damaged wheel without the employment of ajack or any other auxiliary raising device.

The invention consists in providing an auxiliary rim with a pivotedclamping device which enables this rim to be connected with the damagedwheel, this connection being efiected at the point where the two rimsmeet or are disposed opposite each other and in providing the wheel rimwith a supporting device, so that when the vehicle is moved forward orbackward, the auxiliary rim which is provided with an inflated tireraises and centers the damaged wheel within the auxiliary rim when thevertical line of the point of support on the ground passes between thepivoted clamping device and the supporting device, this latter comingagainst the inner face of the auxiliary rim. The two devices, thepivoted clamping device and the supporting device, then serve forrigidly connecting the two rims.

In the annexed drawing given by way of example, Figure 1 illustrates adamaged wheel and an auxiliary rim ready to raise and center it; Fig. 2is a plan of the pivoted clamping device, fixed to the auxiliary rim;Fig. 3 is a section thereof through A-A; Fig. 4 is an end View; Fig. 5is a partial section of the connecting device that is fixed to thedamaged wheel.

In Fig. 1, R is the rim of the damaged wheel, the center of which is atc, the tire having been removed. R is the auxiliary rim, provided withan inflated tire, and having its center at 0 The two rims R and B havepractically the same diameter and the auxiliary rim R carries a clampingdevice a pivotally connected at a and ena ling the two rims to beconnected by means of a tightening cheek. The auxiliary rim R is placedagainst the wheel rim B so that their centers 0 and c are one above theother and the connecting device a is at the point where the two rimsoverlap as indicated in Fig. 1. At a suitable point in the damaged rim Ra supporting device I) is fixed.

When the rims R and R are connected by means of the device a the checkof which is tightened up against the rim R it is only necessary to movethe vehicle forward or backward to bring the vertical line of the pointof support on the ground between the connecting member a and thesupporting member I). This movement will raise the rim R to bring itscenter in the geometrical axis of the center of the rim R At the sametime the supporting member I), which is fixed to the rim R comes againstthe inner face of the rim R taking the position 6 indicated in dottedlines, the points of thiS member I) having described a circle around theaxis of rOtatiOn a of the member a that i fixed to the rim R The rim Ris thus held centered on the rim R and in order to effect a rigidconnection it is only necessary to connect the member b with the rim Rand, according to the weight of the vehicle, to add one or moresupplementary connecting members, suitably distributed over thecircumference of the rims.

Figs. 2 and 4 illustrate one of the forms of construction of the pivotedclamping member a. This member is fixed to the rim R by means of abearing 9 riveted on to the rim (Fig. 4). This bearing carries therotating pin a on which is mounted a block 5 which has a conical part 7the inclination of which corresponds to that of the rim R and permitsthe rotation of R around the pivot 11. Integral with the block 5 is asleeve 6 into which a rod 2 runs the screwthreaded end 4 of which isprovided with a winged nut 10. On the other end of the rod 2 the cheek 1is fixed that can be tightened up against the rim R of the damagedwheel. The nut 10 has teeth 10 (Fig. 4) which can be engaged by a safetybolt 11 (Fig. 3) intended to prevent untightening.

The connecting member I) which is secured on the rim that is to berelieved is in part similar to the connecting member a. Fig. 5 shows thepart that differs. The part not shown to the left of the line B B issimilar to the corresponding part of the member a (Fig. 3) In the caseof the member 12 (Fig. 5) the bearing 9 is fixed on the rod 8 withoutbeing able to rotate thereon.

This bearing may terminate in a dished part 9. A hooked yoke or stirrup12 may be fixed by a nut for the purpose of connecting the clamp 12 tothe rim. R. It is. of course understood that this construction of theconnecting members is only given by Way of example.

I claim as my invention:

1. A device for automatically raising and centering a vehicle wheel,comprising. an. auxiliary rim, a, clamping member mounted onv said:auxiliary rim having means for engaging the rim of the. wheel to beraised at the point- Where said wheel and auxiliary rims overlap, asupporting member carried by the nim, ot the wheel to be raised andhaving means for engaging the auxiliary rimtor locking the rims togetherafter the wheel has been centered.

2: A device for raising and centering a, vehicle wheel, comprising an.auxiliary rim provided with a,- pivoted. member having means forengaging the wheel to. be raised at the point where the wheel. andauxiliary rims overlap.

3. A device for automatically raising and.

centering a, vehicle Wheel, comprising. an auxi'liary rim provlded withan inflated; tire,

ofthe wheel to be raised.

4,. A device for automatically raising and centering a vehicle rim,comprising an auxiliary rim provided with an inflated tire,

a member carried by said auxiliary rim and provided with acheek, forengaging the rim of the wheel to be raised, and means carried by the rimof the wheel to be raised for locking said, rim to said auxiliary rim.

5. A device for automatically raising and centering a vehicle wheel,comprising, an auxiliary rim provided with a pivoted clamping memberhaving a bearing. therein, a rod mounted to slide in said bearing andvprovidedon one end with a cheek for'engaging the rim of the wheel to beraised, the other end ofsaid rod, being threaded, and a tightening nutengaged with the. threaded end of said rod; for drawing. said cheek intoengagement: with said wheel rim.

In: testimony whereof I have afiixed; my signature, in presence of twowitnesses.
